RESUMO
Objective To investigate the possibility of neutrophil-to-lymphocyte ratio (NLR),platelet-to-lymphocyte ratio (PLR) and mean platelet volume (MPV) as biomarker for early atherosclerosis in patients with newly diagnosed type 2 diabetes.Methods 420 newly diagnosed type 2 diabetes were enrolled in the study.They were divided into three groups:patients with normal carotid artery were group A (n =152),patients with unilateral carotid plaque were group B (n =138),patients with bilateral carotid plaque were group C (n =130).Their neutrophil,lymphocyte,mean platelet volume,lipid and glucose,carotid intimal medial thickness (CIMT),ankle brachial index (ABI) were all performed in these individuals.Results Compared with group A,the age,systolic pressure,neutrophil count (NC),platelet count (PLT),NLR,PLR,low density lipoprotein-cholesterol (LDL-C),total cholesterol (TC),fasting blood glucose (FBG),hemoglobin A1c (HbA1c) and CIMT were higher while ABI were lower in group B and group C;Compared with group B,the age,systolic pressure,NC,PLT,NLR,PLR,LDL-C,TC,CIMT and were higher while ABI was lower in group C (P ＜ 0.05).CIMT was positively correlated to age,systolic pressure,NLR,PLR,LDL-C,TC,FBG and HbA1c (P ＜ 0.05) while ABI was negtively correlated to age,NLR,PLR,LDL-C,FBG and HbA1c (P ＜ 0.05).In multiple linear regression analyses,after adjustment for age,lipid,glucose and so on,NLR and PLR were also significantly correlated to CIMT and ABI.Conclusions NLR and PLR were significantly correlated with CIMT and ABI in newly diagnosed type 2 diabetes.Therefore,NLR and PLR may have the potential to serve as biomarkers for early arteriosclerosis in type 2 diabetic patients.
RESUMO
Objective To investigate the correlation of platelets-to-lymphocyte ratio (PLR) with neutrophil-to-lymphocyte ratio (NLR) from pretreatment in the Xinjiang Uygur patients with nasopharyngeal carcinoma.Methods In this retrospective analysis,96 cases of nasopharyngeal carcinoma patients with pathologically diagnosis were collected.Receiver operating characteristic (ROC) curve analysis suggested that optimum PLR and NLR cut-off point for nasopharyngeal carcinoma.The patients were divided into high-PLR and low-PLR groups,high-NLR and low-NLR groups,respectively.The survival rate was calculated with Kaplan-Meier method.The Log rank statistics was used to test differences between groups.The prognostic factors that may affect patients with nasopharyngeal carcinoma in Uighur population of Xinjiang were analyzed by COX proportional hazards models.Results For high-PLR and low-PLR groups,5-year overall survival,and progression-free survival were 46.6％ and 79.3％,49.8％ and 82.7％,respectively;the difference was statistically significant (all P ＜ 0.01).For high-NLR and low-NLR groups,5-year overall survival rate,and progression-free survival rate were 41.3％ and 41.3％,50.8％ and 82.5％,respectively;the difference was statistically significant (all P ＜ 0.01).Univariate analysis showed that N stage,clinical stage,NLR,and PLR had significantly impact on overall survival and progression-free survival (all P ＜ 0.05);multivariate analysis showed that PLR and clinical stage had statistical significance in Uighur patients with nasopharyngeal carcinoma for progression-free survival and overall survival (all P ＜ 0.05).Conclusions PLR may be independent factor that influences the prognosis of patients with nasopharyngeal carcinoma in Uighur population of Xinjiang.
